A number of catalysts based on group 5, 6, and 9 transition metals (Nb, Ta, Mo, W, and Rh) have been developed by us for the polymerization of substituted acetylenes. By using these catalysts, many new substituted polyacetylenes have been synthesized, whose molecular weights are very high. Most of the polymers are soluble in many common solvents and stable enough in air unlike polyacetylene. Further, living polymerization of phenylacetylene was achieved by use of Rh-vinyl complexes. Precision polymer synthesis of substituted polyacetylenes including polymer brushes has also been enabled. We have found that N-propargylamides and other substituted acetylenes having suitable chiral groups polymerize with Rh catalysts. The formed polymers exhibit large specific rotations and strong CD signals, indicating that their main chain adopts a helical conformation with predominantly one-handed screw sense. We have been studying the synthesis and properties of highly gas-permeable substituted polyacetylenes. In this lecture, the synthesis and functions of these polymers as well as other novel functional polymers are introduced. 1) T. Masuda, A. Zhang, In “Handbook of Metathesis, Second Ed.”, R. H.
